A court in Athens has convicted six members of the Greek militant group Conspiracy of the Cells of Fire for three separate terrorist bombings in 2009.

The six were given prison terms Tuesday ranging from 11 to 25 years. A sixth member of the group was sentenced on charges unrelated to the bombings. Two members were acquitted.

The militants attacked the homes of former Deputy Public Order Minister Panagiotis Hinofotis and PASOK politician Louka Katseli in 2009. The offices of the ministry in charge of the Macedonia-Thrace region of northern Greece also were bombed. No one was hurt in any of the attacks.

The Conspiracy of the Cells of Fire also claimed responsibility for last year’s wave of parcel bombs sent to European leaders and foreign embassies in Athens.
